1 Claim. 1

This invention relates to barrel tapping means, and the main object is the provision of a novel, useful and practical barrel bung bit by means of which a barrel may be easily tapped, and the flow from the barrel may be either completely stopped or regulated, including, of course, the starting of the flow whenever desired. The device may be used in connection with barrels or containers of liquid or free-flowing powdered or granular material.

The above broad as well as additional and more specific objects will be clarified in the following description wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended solely for the purpose of illustration and that it is therefore neither desired nor intended to limit the invention necessarily to any or all of the exact details of construction shown or described except insofar as they may be deemed essential to the invention.

Referring briefly to the drawing,

Fig. 1 is a perspective View of a barrel bung bit embodying the present invention.

Fig. 2 is a fragmentary sectional view of a barrel taken on a horizontal plane through the bung hole of the barrel and with the bit of this invention positioned in the said hole, illustrating an application of the invention, the said bit being partly broken away and partly in section. r

Fig. 3 is a fragmentary view similar to Fig. 2, showing, however, the barrel bung bit partway withdrawn from the bung hole.

Referring in detail to the drawing, the numeral It) indicates a barrel having the usual bung I2 positioned in the usual bung hole l I. Normally, as is well known, such barrels are tapped by removing the bung l2, and they are subsequently closed by restoring the bung l2 into the hole II. This is a laborious and crude method of access to and closure of the barrel, the disadvantages of which are too many and too well known to require elucidation.

The barrel bung bit of this invention comprises the implement or tool l3 which includes the shank l4 and the handle l5. The lower portion of the shank I4 is constructed in the form of, first, a gimlet It at the bottom and, second, a wood screw [1 above the gimlet it, the body of the wood screw portion I! having, not including the threads l8 thereon, a constant diameter approximately equal to the diameter of the upper end Ilia of the gimlet iii.

The gimlet end It of the device is constructed in accordance with the usual design of a gimlet,

that is, it comprises a spiral shell the diameter and pitch of the lobes of which increase in a direction upward from the tip 20, as indicated at l9. Hence the shell H! has a passage 2| extending generally longitudinally of the gimlet from a point just above the tip 20 to the upper end of the gimlet where the said passage is blocked by the wall 22 constituting part of the lower end of the threaded body ll.

Through this lower wall 22 and extending longitudinally along the body I! for a distance, a groove 23 is cut into the threaded body I! thus providing an extension of the gimlet passage 2|. The groove 23 extends upward along the screw body I! only partway, as illustrated.

In use, instead of having to knock out the bung l2 from a barrel in order to tap it, the implement I3 is applied to the bung and the gimlet end is screwed through the bung thereby providing an opening 24 therethrough. Assuming that Fig. 3 shows the implement in the act of drilling the hole 24 in the bung, it is apparent that as the implement is further turned the threaded body I! will continue to enter the hole. In the position of the said body shown in Fig. 3, liquid may flow from the barrel through the continuous passage 2|, 23, but further advance of the shank into the hole will result in stopping such flow as soon as the upper end of the groove 23 becomes positioned entirely within the hole 24, as shown in Fig. 2. Of course, by having the groove 24 extend a shorter distance upward than that illustrated in the drawing, the flow may be stopped sooner.

Once the bit has thus been entered through the bung and remains positioned therein in, for example, the position shown in Fig. 2, it is apparent that flow from the barrel may be started quickly by merely turning the shank to unscrew the body I! partway from the hole 24 to expose the upper end of the groove 24 outside the barrel. It is also apparent that the degree of such flow may be regulated by varying the extent of the exposure of the upper end of the groove 24 outside the barrel. And likewise the flow may be quickly cut off and the barrel plugged.

Thus a very useful, practical and convenient barrel bung bit has been provided for the purposes set forth, which is at the same time inexpensive in cost of manufacture.

Obviously, modifications in form or structure may be made without departing from the spirit or scope of the invention.

I claim:

A barrel bung bit comprising a shank adapted to be rotated on its axis, the lower end of said shank having a gimlet thereon, said gimlet having a generally longitudinally extending passage extending from the tip thereof to the upper end thereof, said shank having a cylindrical body portion positioned thereon above said gimlet and extending for a distance from the upper end of the gimlet, said body portion having substantially the same diameter as said upper end of the gimlet, said body portion having screw threads thereon of greater diameter than said firstnamed diameter, said body portion including said screw threads having a longitudinal groove therein communicating with the upper extremity of said gimlet passage, said groove having the upper 15 of said groove being constant and being smaller than the cross-sectional area of the upper extremity of the gimlet passage.
